(a) Poisson (b) Pascal (c) Normal (d) Binomial (e) Geometric Which of the following sample size gives the smallest type I error in an X chart? (a) n-2 (b) n-4 (c) n-5 (d) n-7 (e) type I error is not determined by n

Answer 1

The percentages of the specification band used by any process is calculated by the following formula,

= 100/1.5 = 66.6666

67%
